The old town of Tuzla, with its mix of Ottoman and Austro-Hungarian buildings, mosques, churches and the Kapija square, along with museums telling the story of the citys salt-mining heritage, offers a rich cultural experience. Ticketed museum displays explain how salt shaped the city over thousands of years and caused the ground subsidence that created the Pannonian Lakes. Exploring the old town and its museums is the best way to understand the unique history and character of the city.
